ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength

R. Liseau, W. Vlemmings, A. Bayo +19

The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…

Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate

Nick Indriolo, D. A. Neufeld, M. Gerin +19

In diffuse interstellar clouds the chemistry that leads to the formation of the oxygen bearing ions OH+, H2O+, and H3O+ begins with the ionization of atomic hydrogen by cosmic rays…

Resolving the shocked gas in HH54 with Herschel: CO line mapping at high spatial and spectral resolution

P. Bjerkeli, R. Liseau, C. Brinch +11

The HH54 shock is a Herbig-Haro object, located in the nearby Chamaeleon II cloud. Observed CO line profiles are due to a complex distribution in density, temperature, velocity, an…

Herschel HIFI observations of O toward Orion: special conditions for shock enhanced emission

Jo-Hsin Chen, Paul F. Goldsmith, Serena Viti +18

We report observations of molecular oxygen (O) rotational transitions at 487 GHz, 774 GHz, and 1121 GHz toward Orion Peak A. The O2 lines at 487 GHz and 774 GHz are detected at…

Detection of chloronium and measurement of the 35Cl/37Cl isotopic ratio at z=0.89 toward PKS1830-211

S. Muller, J. H. Black, M. Guelin +11

We report the first extragalactic detection of chloronium (H2Cl+), in the z=0.89 absorber in front of the lensed blazar PKS1830-211. The ion is detected through its 1_11-0_00 line…

An ALMA Early Science survey of molecular absorption lines toward PKS1830-211 -- Analysis of the absorption profiles

S. Muller, F. Combes, M. Guelin +17

We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z=0.89 molecular absorber toward the lensed blazar PKS1830…
